[Feature #18885]
For now, the optimizations performed are:
- Run a major GC
- Compact the heap
- Promote all surviving objects to oldgen
Other optimizations may follow.
Introduce Universal Parser mode for the parser.
This commit includes these changes:
* Introduce `UNIVERSAL_PARSER` macro. All of CRuby related functions
are passed via `struct rb_parser_config_struct` when this macro is enabled.
* Add CI task with 'cppflags=-DUNIVERSAL_PARSER' for ubuntu.
* Add rb_io_path and rb_io_open_descriptor.
* Use rb_io_open_descriptor to create PTY objects
* Rename FMODE_PREP -> FMODE_EXTERNAL and expose it
FMODE_PREP I believe refers to the concept of a "pre-prepared" file, but
FMODE_EXTERNAL is clearer about what the file descriptor represents and
aligns with language in the IO::Buffer module.
* Ensure that rb_io_open_descriptor closes the FD if it fails
If FMODE_EXTERNAL is not set, then it's guaranteed that Ruby will be
responsible for closing your file, eventually, if you pass it to
rb_io_open_descriptor, even if it raises an exception.
* Rename IS_EXTERNAL_FD -> RUBY_IO_EXTERNAL_P
* Expose `rb_io_closed_p`.
* Add `rb_io_mode` to get IO mode.

When one thread is closing a file descriptor whilst another thread is
concurrently reading it, we need to wait for the reading thread to be
done with it to prevent a potential EBADF (or, worse, file descriptor
reuse).
At the moment, that is done by keeping a list of threads still using the
file descriptor in io_close_fptr. It then continually calls
rb_thread_schedule() in fptr_finalize_flush until said list is empty.
That busy-looping seems to behave rather poorly on some OS's,
particulary FreeBSD. It can cause the TestIO#test_race_gets_and_close
test to fail (even with its very long 200 second timeout) because the
closing thread starves out the using thread.
To fix that, I introduce the concept of struct rb_io_close_wait_list; a
list of threads still using a file descriptor that we want to close. We
call `rb_notify_fd_close` to let the thread scheduler know we're closing
a FD, which fills the list with threads. Then, we call
rb_notify_fd_close_wait which will block the thread until all of the
still-using threads are done.
This is implemented with a condition variable sleep, so no busy-looping
is required.
Let signal.c include "internal/error.h" explicitly to ensure that the
identifier rb_sys_fail_str in signal.c refers to the macro defined in
"internal/error.h" instead of the actual function.
That macro reads errno before evaluating its argument. Without this
change, the rb_signo2signm(sig) expression in the "trap" function in
signal.c will overwrite the errno before the actual rb_sys_fail_str
function reads the errno.

This new `peformance` warning category is disabled by default.
It needs to be specifically enabled via `-W:performance` or `Warning[:performance] = true`
The socket extensions rubysocket.h pulls in the "private" include/gc.h,
which now depends on vm_core.h. vm_core.h pulls in id.h
when tool/update-deps generates the dependencies for the makefiles, it
generates the line for id.h to be based on VPATH, which is configured in
the extconf.rb for each of the extensions. By default VPATH does not
include the actual source directory of the current Ruby so the
dependency fails to resolve and linking fails.
We need to append the topdir and top_srcdir to VPATH to have the
dependancy picked up correctly (and I believe we need both of these to
cope with in-tree and out-of-tree builds).
I copied this from the approach taken in
https://github.com/ruby/ruby/blob/master/ext/objspace/extconf.rb#L3

btest can't be used for testing RJIT because RJIT doesn't work on
miniruby. However, btest-ruby is not necessarily useful for testing RJIT
because both the runner could crash as well as the target.
TBH I'm not sure why we want to use RUNRUBY instead of BOOTSTRAPRUBY on
btest-ruby. However, to achieve what I want to do while keeping the
current behavior, I'm just introducing a new target.
These classes don't belong in gc.c as they're not actually part of the
GC. This commit refactors the code by moving all the code into a
weakmap.c file.
We used to require MJIT is supported when YJIT is supported. However,
now that RJIT dropped some platforms that YJIT supports, it no longer
makes sense. We should be able to enable only YJIT, and vice versa.
